SLURRYCUP™ GRIT WASHING AND SLUDGE DEGRITTING
The “all-hydraulic” design of the SLURRYCUP™ has no internal moving parts, which increases reliability. Two levels of “washing” produces clean grit ready for dewatering. Failure to effectively remove all grit abrasives results in downstream plugging and excessive wear on mechanical equipment.

CAPTURES 95% OF ALL GRIT 50 MICRON AND LARGER
The SLURRYCUP™ is extremely effective at washing grit captured at the preliminary treatment stage by the grit channel, aerated grit chamber, vortex grit collector, or settleable solids concentrator. The SLURRYCUP™ minimizes organic content which reduces objectionable odors and reduces the volume hauled to landfill. The SLURRYCUP™ meets the challenges of separating and classifying grit as small as 50 micron (270 mesh).

Primary sludge degritting minimizes deposits in anaerobic digesters and reduces abrasive wear on pumps, centrifuges, and other downstream equipment. This can be the most economical location in a wastewater treatment plant to remove grit. The SLURRYCUP™ uses two levels of separation and classification to capture and wash very fine, as small as 50 micron sand, from primary sludge up to 1.5% total solids.

The SLURRYCUP™ uses a combination of an open free vortex and the boundary layer effect to capture, classify, and remove fine grit, sugar sand, snail shells, and high density fixed solids from grit slurries, and both primary and secondary sludge.

The grit underflow from the SLURRYCUP™ passes through a hydraulic valve which provides secondary grit washing. The cleaned grit slurry, when dewatered by a GRIT SNAIL™, contains 60% total solids with less than 20% unattached volatile or organic solids. Reduced organic solids content minimizes the volume and weight hauled to solid waste disposal sites. It also reduces odors and associated complaints.
